tailieunhanh - Selection of stable groundnut genotypes (Arachis hypogaea) for manipur valley condition

Stability analysis in groundnut (Arachis hypogaea) for thirteen promising genotypes was conducted during kharif 2009-10 for estimation of stability parameters with respect to pod yield and its components in five different environments of Manipur valley. Analysis of variance revealed that there were significant differences among the genotypes for all the characters under study. The study of stability parameters in the present investigation revealed that among the environments, the E-1 (Thamnapokpi) was the best yield and its components while the E-5 environment (Iroisemba) was the lowest for yield and its component. The better genotype for the phenotypic stability of pod yield and its component were found to be M 335(NC) and it could be recommended for general cultivation over a wide environmental condition in Manipur valley. The better genotypes under favourable environments for yield and its components were found to be Kaushal and CSMG 03-07 and they could be recommended for cultivation under suitable soil condition and high input management. Under unfavourable environment, the better performing genotype was found to be HNG 123 and ICGS 76 and therefore, it could be recommended for cultivation under poor/low management conditions. | Selection of stable groundnut genotypes (Arachis hypogaea) for manipur valley condition
